Description

The present invention relates to the field of automotive wheel hub processing, and in particular to an automatic material feeding device for automotive wheel hubs.

As the starting end of the wheel hub machining workshop, the material feeding device for wheel hub machining is an essential part. Also, in automated production lines, it is even more essential to reduce the use of workers, improve production efficiency, and provide fast and efficient material feeding equipment. Currently, in most small and medium-sized enterprises, loading and unloading materials and transporting wheel hubs are still performed by workers, which not only reduces efficiency but also increases the workload of workers.

In the prior art, U.S. Pat. No. 5,001,302 discloses a bearing cage material feeding mechanism that includes a base turntable, a material rack, a horizontal manipulator, and a vertical manipulator. The vertical manipulator pushes and lifts the material rack in the axial direction, and the horizontal manipulator carries the material to realize material feeding. This kind of bearing cage material feeding device can carry out material feeding continuously, but the pushing movement claw body finishes feeding the workpiece to the material rack, and then moves upward from the material rack, and then moves to the base Since it is necessary to rotate the turntable and switch to the next material rack, the push-motion pawl body is always located under the bearing cage. Therefore, the base turntable can only be rotated after feeding the last bearing cage of the material rack. , so even if the last bearing cage is defective, its feeding must be terminated, and then the pushing movement claw body must be removed and the base turntable must be rotated to replace the material rack. , which causes defective products to enter the machining part and cause unnecessary damage to the processing equipment in the workshop. US Pat. No. 5,900,301 discloses a wheel hub material supply apparatus that includes a frame, a lift arm assembly, a translation assembly, and a clamp pawl assembly. When feeding material, the material is fed to the top wheel hub of the material rack every time, and after feeding the material once, the lower wheel hub moves up to realize the top material feeding. Also, if the material rack needs to be replaced, simply remove the material rack from the device, rotate it, and then replace it. Although the device of Patent Document 2 can complete uninterrupted feeding, it does not take into account how the wheel hub appears on the material rack, and only applies to wheel hubs that are already on the material rack. Therefore, after the wheel hub on the material rack is processed, the wheel hub on the material rack can only be carried into the material rack, and the material rack is a fixed cylinder without layering, and after being separated from the feeding device. cannot be used, which reduces efficiency and makes it impossible to meet continuous supply needs. Patent Document 3 discloses an intelligent mechanical automatic material feeding device, which uses a vacuum pump to evacuate the material to firmly adsorb the material, and completes the feeding through the cooperation of gears, bracket slide rails, etc. However, this device has major limitations because vacuum suction cannot adsorb curved or complex surfaces, and it can only feed material placed on the surface of the material rack, and the material rack is divided into multiple layers. If so, the device cannot complete the material feeding function. Patent Document 4 discloses an automatic material feeding device. This patented automatic material feeding device feeds the material randomly by mechanical vibration, and the material whose posture does not meet the requirements is vibrated again to feed the material, so it is highly versatile and can be used for a variety of different shapes. Can be adapted to materials. However, this device is insufficiently capable of continuous material feeding for processing and cannot meet the requirements of continuous operation.

In summary, currently most automotive wheel hub material supplies are transported manually, which is inefficient and imposes a large workload. The feeding device already has some problems to overcome, making it inconvenient to use in factories. For example, replacing the material rack is not convenient, and the material rack cannot meet the performance of wheel hub storage after being separated from the material feeding device, and may be unstable when the material feeding device grabs the material. However, there are problems such as the wheel hub being damaged during the material feeding process, making it impossible to ensure the efficiency and stability of the material feeding process.
